stitutes the subject matter of my prior lietters Patent No. 1,287,503, dated December 10, 1918, and in which the film supporting and operating mechanisms aremounted in a shell or housing as a complete and assembled unit for attachment within the main,

inclosing casing of the machine. And the present improvement has for its object To provide a simple, compact and efficient structural formation and association of parts wherein the driving motor of an electric type, with its reversing switch are mounted as a part of the above mentioned assembled unit, and adapted to afford a power driven means for winding and unwinding the picture film upon the com panion film reels of the machine, all as will hereinafter more fully appear.

ln the accompanying drawings Figure 1 is a detail side elevation illusstrating the general structural arrangement of the present improvement as applied to the motion picture machine shown in my aforesaid Letters lDatent No. 1,287,503, parts of the supporting shell or housing being broken away to show the arrangement of the reversing switch of the electric motor.

Fig. 2 is a detail front elevation of the shell or housing and associated electric motor and its reversing switch.

Fig. 3 is a fragmentary longitudinal section on line 3-? Fig. 2.

Lilie Vreference numerals indicate ylike parts in the several views.

Referring to the drawings, 1 designates a portion of the front wall of the. main inclosing box or casing of a portable motion picture machine, to the inner face of which is secured an inclosing shell or housing 2 in which is mounted and contained the picture film guiding and actuating means and mechanisms, as well as the light controlling shutter of a machine, such as described in my aforesaid Letters Patent No. 1,287,583.

Serial En.

3 designates the Ltramsversely arranged primary driving shaft of the above mentioned mechanisms, provided at one end with the usual driving pulley e, preferably of the heavy fly wheel type as shown.

5 designates a vertically disposed enlarged portion of the shell or housing 2, providing a shallow containing chamber for the light shutter of the machine as set forth in my former Letters ljatent No. 1,287,563, and in the'present construction 6 designates an enlarged open front portion of the shell or housing 2, arranged forward of the aforesaid enlarged portion 5 and adapte l to provide a containing chamber forthe reversing switch 7 of the electric motor 8 used as the driving means of the machine.

9 designates a depending portion of the aforesaid enlarged front portion 6, formed at its lower end with a -curved frange 10 forming a seat for the shell of the motor 8, which is secured in place' by screw bolts 11, as shown in Figs. 2 and 3.

The reversing switch 7, above referred to, may be of any usual type, preferably of the semi-rotary snap switch type shown, and having a handled operating shaft l2 disposed in a sunken socket plate 13 in the front wall ofthe main casing 1 'for convenient manual operation.

14 designate line wires or conductors between the reversin switch 7 and the electric motor 8, arrange in. the chamber of the aforesaid front portion 6 of the shell or housing 2.

15 designates a pulley mounted on the armature shaft of the electric motor Sand having an endless belt connection 18 with the pulley i of the aforesaid primary shaft 3 of the lm actuating mechanism.

17 designates a spring actuated belt tightener, the carrying arm 18 of which is pivoted to the depending ,shell portion 9 of the shell or housing 2 aforesaid.

Having thus fully described my said invention what .l claim as new and desire to secure by Letters Patent, is

1. ln a motion picture machine, the combination of a shell or housing forming a sup: port for a lm actuating mechanism and its primary driving shaft, said shell having a seat on its under side, amotor having an in-4 closing shell attached to said seat, and opesV bination of a shell or housing forming a sup.

port for a film actuating mechanism and its primary driving shaft, said shell having an open front containing chamber and a Seat on its under side, .a' reversing switch arranged in said open front chamber, a motor having an inclosing shell attached to said seat, andoperative connections between the shaft of said`motor and the primary shaft aforesaid substantially as set forth.

3. In a motion icture machine, the combination of a shel or housing forming a support for a film actuating mechanism and its primary driving shaft, said shell having an enlarged front portion' the lower depending part of which is formed with a seat, a motor having an inclosing shell attached to said seat, and operative connections between the shaft of said motor and the primar shaft aforesaid substantially as set fort 4. In a motion picture machine, the combination of a shell or housing forming a support for a film actuating mechanism and its primary driving shaft, said shell havin an enlarged front portion the lower depening part of which is formed with a curved flange, a motor having an inclosing shell attaining c lower depending part, a reversing switchv arranged in said containing chamber, a motor having an inclosing shell attached to said seat, and operative connections between the shaft of said motor and the primary shaft aforesaid.

6. In a motion picture machine, the combination of a shell or housing forming a support for a film actuating mechanism and its primary driving shaft, said shell having an enlargled front vportion forming a conamber and with a curvedy flange on the lower depending part of the same,

a reversing switch arranged'in said containing chamber, a motor having an inclosing shell attached to said flange, and operative connections between the shaft of said motor and the primary shaft aforesaid, substantially as set forth.
